                MQTT stands for MQ Telemetry Transport. It is a publish/subscribe, 
                extremely simple and lightweight messaging protocol, 
                designed for constrained devices and low-bandwidth, 
                high-latency or unreliable networks. 
                The design principles are to minimise network bandwidth and 
                device resource requirements whilst also attempting to ensure 
                reliability and some degree of assurance of delivery. 
                These principles also turn out to make the protocol ideal of the emerging “machine-to-machine” (M2M) or 
                “Internet of Things” world of connected devices, and for mobile applications 
                where bandwidth and battery power are at a premium.
